Fiber Optic Ringlightsfiber optic ringlights

  • Uniform Illumination
  • Shadow-free
  • Full-circular
  • High intensity
  • Adaptable to all microscope brands Use Volpi cold light sources

Full circular glass fiber ringlights provide homogeneous, shadow-free illumination for working distances from 25 to 90 mm. The M10 Compact Ringlight has working distances from 15 to 70 mm. The ringlight inside diameter is 66 mm for mounting on all microscope objectives through a series of ringlight adapters. Ringlight cables have a standard flexible length of 750 mm (30 in). Longer lengths are available.


Ergo/Olympus SZ/SD Fiber Optic Ringlight Ergo Olympus ring set

  • Ergonomic
  • Long working distance starting at 100 mm
  • Direct mounting to Olympus
  • Use Volpi cold light sources

A tapered ringlight used for direct mounting on Olympus SZ/SD Microscopes with minimum loss of working distance. Flexible length exits at 45° angle allowing maximum work space. Its working distance starts at 100 mm with longer flexible lengths available. Adapter is included.

 The Ring Polarizer Set, Toric Lens, Diffuser, and Fluorescence Filter Set are useful components for the illumination of microscopic fields.

  • Polarization
  • Diffusion
  • Low intensity fluorescence
  • Reduce or eliminate unwanted reflections
  • Extend standard ringlight working distance range
  • Used with standard, compact and 4-point standard ringlights
  • Use Volpi cold light sources

The Ring Polarizer Set eliminates unwanted reflections of highly reflecting materials such as tissue and metallic objects. Glass analyzer is used with plastic polarizer for the best possible cross-polarization effect. It can be used with Standard, Compact, and 4-Point Standard Ringlights.

The Toric Lens extends the working distance of Standard and Compact Ringlights from 90 to 150 mm. Longer distance ringlights are also available as an alternative.

The Diffuser reduces unwanted reflections of highly reflecting materials such as tissue and metallic objects. Can be used with Standard, Compact, and 4-Point Standard Ringlights.


Glass Fiber BacklightsGas Fiber Backlights

Glass Fiber Backlights provide homogeneous, diffuse illumination. The glass fiber used is extremely durable and heat tolerant. These backlights can be adapted to most common brand microscope bases. A ± 10% output uniformity is guaranteed for the central 90° area. All output uniformity measurements are made using an industry standard EKE lamp operating at full intensity.

  • Homogeneous Fiber Optic Illumination
  • Diffuse with High Intensity
  • Highly uniform illumination (± lO%) for image processing
  • Brightfield illumination on stereo microscopes enables pattern recognition of different transparencies
  • Also enables area recognition of different colors, side illumination, dimensional gauging, and shape verification
  • Luminance - 7500 cd/m2
  • Glass Fiber - High Heat Tolerance
